Abstract
The polymerization of n-butylsilane catalyzed by Cp 2 ZrMe 2 yields low molecular weight catenated Si-Si oligomers with a large percentage of the Si 5 through Si 7 cyclic oligomers. Oligomers with degrees of polymerization (Dp) of 2 through 8 were also observed showing clear demonstraton of a step growth mechanism. The difference in products is believed to be due to the ability of zirconium to react reversibly with both primary and secondary alkylsilanes
